(1991)Type: Journal ArticleThe role of small fishes in the diet of the rural poor in Bangladesh is described. Basic statistics (maximum size reached, length-weight relationships and prices) are presented for 42 species, belonging to 10 families and ... -
A qualitative method for modelling integrated aquaculture agriculture farming systems
(1991)Type: Journal ArticleIntegrated aquaculture-agriculture farming systems are defined as sys tems where the outputs from aquaculture become inputs to agricultural enterprises and vice versa, resulting in a greater total effect than the sum of ... -
Biochemical and morphometric approaches to characterize farmed tilapias
(1991)Type: Journal ArticleBiochemical (electrophoresis and mitochondrial DNA) and morphological analysis are important tools for the characterization of strains. Reference is made to studies conducted in the framework of the Genetic Improvement of ... -
Growth performance of a planktivorous clariid, Bathyclarias loweae, in an experimental pond
(1991)Type: Journal ArticleA brief account is given of a fish culture trial conducted in Malawi to determine the growth performance of Bathyclarias loweae and its potential for aquaculture. -
Simple aquaculture training for rural development in Zimbabwe
(1991)Type: Journal ArticleA summary is provided of a course introduced in 1987 at the Chaminuka Training Centre in Zimbabwe for training in rural aquaculture. The recruitment of trainees, aquaculture and rural development, the curriculum and practical ... -
Estimation of yield per recruit when growth and fishing mortality oscillate seasonally
(1991)Type: Journal ArticleA general form of the yield equation is presented. This is used to investigate the effects of seasonal growth oscillations on estimation of yield per recruit. The results show that these effects will be strongest in ... -
Growth of Pomadasys kaakan (Haemulidae) off the coast of Pakistan
(1991)Type: Journal ArticleThe growth parameters of javelin grunter Pomadasys kaakan (=P. hasta, Haemulidae) were estimated from length-frequency samples collected from December 1988 to February 1989 along the Pakistan coast. They are L sub( infinity ... -

Report on BARC/ICLARM/USAID Workshop on "Inland Aquaculture Development Strategies for Bangladesh", 29 September - 01 October 1991
(1991)Type: ReportFish and fisheries play an important role in the economy, nutrition and employment, in Bangladesh. In recent years, there has been a decline in per caput consumption of fish, which contributes some 71% of total animal ... -
Growth, mortality and recruitment of Decapterus kurroides in Davao Gulf, Philippines
(1991)Type: Journal ArticleThe ringnet fishery off Davao, southern Philippines, is briefly described. The major species (36%) in the catch is Decapterus kurroides (Pisces, Carangidae), whose growth parameters and mortality rates (natural and fishing) ... -
Concurrent rice-fish trials: comparing regular and border planting patterns
(1991)Type: Journal ArticleDetails are given of experiments conducted at the Freshwater Aquaculture Centre at Munoz, Philippines, to investigate the effects of varying the rice planting pattern on fish yields in integrated rice field aquaculture ... -
A program for constructing length-converted growth curves when growth is seasonal
(1991)Type: Journal ArticleFollowing Sparre's (1990) demonstration that length-converted catch curves overestimate total mortality when growth is seasonal, Pauly (1990) presented a method for constructing length-converted growth curves that allow ... -

On length-weight relationships. Part II: Computing mean weights from length statistics
(1991)Type: Journal ArticleAssuming a known length-weight relationship, the formula for calculating the mean weight from grouped length statistics is recapitulated. Then a simple analytical method for calculating mean weight from basic length ... -
The context of small-scale integrated agriculture-aquaculture systems in Africa: a case study of Malawi
(1991)Type: Working PaperA study summarizing available literature on aquaculture and small-scale aquaculture in Malawi. It gives a national case study of one African context in which small-scale aquaculture has developed, and in which integrated ... -
Time recovery for exploited fish populations based on surplus yield models
(1991)Type: Journal ArticleA new method to estimate the time recovery of exploited population based on M.B. Schaefer's theory is proposed. The parameters used as follows: current population size (alphaP sub( infinity )'), target population level ... -
